Like n nmbers of reference indicate like parts in each.

The mechanism is contained in a box or case, 1, having front and back sides, 2 and 3, and endse and 5.

Upon the lower end of a shaft, 6, Fig. 2, is a beveled-gear wheel, 7, which meshes into a beveled-gear'wheel, 8, mounted on a shaft, 9, which runs at right angles to the shaft 6. At the upper end. of the shaft 6 is a radial arm or lever, 10, with which, by means of a cord, 11,

extending by sheaves 12 to any desired point,

i the shaft 6 is turned in a forward direction.

CO v

The shaft 6 is retracted or turned backward by means of astro'ng spring, 13, coiled around it, one end of the spring being fastened to the shaft and the other end being fastened to the case at 14, Fig. 2.

Journaled in the box ends 45are two shafts, 15 16, the first at the front and the second at the back of the box. On the end of iheshaft 15 is a beveled pinion, 17, which meshes into the beveled-gear wheel Son the shaft 9,and on the end of the shaft 16 is a beveled pinion, 1.), which .meshesinto the beveled-gear wheel 20 on the shaft 9. Thus the shaft 9 is driven by the shaft 6, and in turn drives the two shafts l5 and 16.

Mounted loosely on the shaft 6, directly under the shaft 10, is a non-rotating (lisk,.2l, which has a ratchet, rack, or quadrant, 22, along the lower edge of the side, around which the arm 10 oscillates, the inclines of the teeth running downward in the direction of the forward movement of the arm.

on the straight sides of the teeth and prevents the spring 13 from throwing the arm back. The rack 22 projects from the lower edge of the periphery of the disk 21, so as to form a sort of a shelf, 25, back of the teeth.

Upon the shaft 6, and pressing up against the disk 21, is a spiral spring, 26, which holds thedisk 21 up against the arm 10, so that the rack 22 shall he in the same horizontal plane as that of thepawl 24, to permit the latter to engage the teeth of the former.-

On the rear end of the arm 10 is a short arm or projection, 27, and on the upper surface of the disk are two reversed inclines, 28 29, which stand in the paths of the arins 10 and 27, so that when the latter come around against them at the end of the forward turn of the shaft 6 they ride up on them and depress the disk 21 against the spiral spring 26. The depression of the disk causes the rack 22 to pass below the plane of the pawl 24, and the latter to.

sition, the pawl, not havingany hold, is unable to prevent the spring 13 from turning the shaft backward, and slides over the smooth shelf until it drops off at the rear end of .the rack. Then the disk 21, being no longer held down by the pawl resting on the shelf, rises and brings the rack to the same level as but in front of the pawl. The arm 10 is limited at this point of its backward movement by a spring stop or buffer, 30. The disk 21 is prevented from turning by having a square side, 31, which abuts against the frame.

On the inner face of the side 2, Fig. 7, are two vertical grooves or ways,32-one near each end. Two slides, 33, of similar construction, are placed in the grooves 32. Along the outer edge of each slide 33 is a rack, 34, which extends some distance beyond the body of the slide, on the end of which is a spring-hook, 35, which is beveled on its top and inner sides, as at 36 and 37, and is fitted with a lateral recess, 38, onits inner side, back of the end bevel. Near the top of the side 2 are two lateral spring-pawls, 39, having beveled ends, which will be stated farther on.

project into the grooves 32 in the path of the slides, and are designed to operate in connection with the beveled ends of thespring books or catches 35. When a pawl, 39, encounters the top bevel 36, it depresses the spring-hook The inner face of the slide 3, Fig 9, is a facsimile of that of the side 2, except that it is inverted-that is to say, it has two vertical grooves, 41, two slides, 42, having racks 43,

spring-hooks 44, beveled and recessed at 45 56' 47, lateral spring-pa-wls 48, which racks are geared into by pinions 49 on the shaft 16, all precisely like the parts on the side 2, except that the side 3, and consequently its attachments, are inverted.

In the upper part of the case, above that part through which the shafts 15 16 extend, is a chamber, 50, Figs. 6,8, and 11, which extends the entire depth of the case between the two sides 2 and 3, and this chamber of a suitable height and length to permit the easy passage through it, in an upright position, of the indicating-plates 51. In the lower part of the case,-below that part through which the shafts 15 16 extend, is a chamber, 52, which is a fac-simile of the chamber 50. Between the chambers 50 and 52 is a boxed-up section, 53, containing the shafts 15 16. The depth of the boxed section 53 is less than that of the chambers 50 52, so as to leave vertical passages 54 and 55 at the front and rear, respectively, of a width sufficient for the easy edgewise passage of the plates 51 from one chamber, 50 or 52, to the other. The chambers 50 52 are for holding the indicating-plates and permitting their passage forward and back in the case, and the passages 54 and 55 are for permitting the passage of the plates from one chamber to another. The movement ofthe platesis forward through the chamber 50, downward through the passage 54, backward through the chamber 52, and then upward through the passage 55 to the chamber 50, thus making a complete circuit of the boxed section 53. In this entire circuit the plates always stand on their lower edge, and they are guided in this circuit by the vertical guides 56-one at each end of the horizontal chambers and vertical passages, and bounding the entire round, so as to form a continuous'guiding or bearing surface for both ends of the plates. The guides 56 also box in the pinions 40 and 49, so that the ends of the plates 51 shall not encounter them.

In the boxed section 53 are eight (more or less) spring-holders, 57 58, four at the front and four at the rear, the ends of which are beveled, and project into the passages 54 and 55. The longer sides of the front holders, 57, are down and those of the rear holders, 5%, are up. (See Fig. 11.)

Below the chamher52, and at the front lower corner of the case, Figs. 2 and 6, is a shaft, 59, the end of which projects through the end 5, and is there provided with an arm, 60, having a slotted lateral projection or lug, 61. One end of a leaf-spring, 62, is fastened to the case at 63 and the other end extends into the slot in the lug 61 and exerts its force to throw the arm forward, and thereby to turn the shaft 59 in that direction. The end of the arm 60 projects back of the sleeve of the beveled pinion 17 and stands in the path of a lug, 64, projecting radially therefrom, so that when the pinion 17 turns the lug 64 comes against the arm 60 and forces it backward until it slips past and releases it. The-operation of the lug 64 on the arm 60 turns the shaft 59 backward; but when the lug 64 slips past the arm 60 and releases it the spring 62 retracts the arm and turns the shaft 59 forward again.

' On the shaft 59 are two or more curved radial arms or pushers, 65, which oscillate with the shaft, whose office it is, when a plate, 51, descends through the passage 54 into thechamber 52 to push it and the other plate back in the chamber, to make place for the next descending plate, and then to withdraw themselves, so that they in turn shall not be in the way of the said next descending plate.

On the rear side of the machine, Fig. 8, are the following parts, which are duplicates of those last-described, but occupy inverted positions,'viz: a shaft, 66, provided with anarm, 66, having a slotted lug, 67, a spring, 68, a lug, 69, on the sleeve of the pinion 19, and curved radial arms or pushers'70. The shaft 66 occupies the upper rear corner of the case and the pushers 70 project downward and inward and push the plates 51 forward in the chamber 50 as they ascend, one by one, through the passage 55.

M432? 1 p s Fastened to the bottom or floor of the chamber 52, and projecting into the passage 54, are

' two or more flat-faced springs, 71, Fig. 11,

forced down-thereupon, so as to depress the springs, for the purpose of certainly carrying the plate clear of the spring-holders'57 and of the edge of the boxed section 53 before it. is forced back into the chamber 50 by the pushers 65.

In the front side, 2, isan opening, 73, Fig. 1, which. may be fitted with a pane of glass, if desired, for exposing to view the name or sig' nal which is on the front side of the indicatingplates.

Theindicat.ing-plates51, Fig. 13, haveabody, 74,ofanydesired length and width.and asquare projection, 75, at each end. The top and bot- 1 tom edges of the body are beveled, as-at 76 and 77,.and also the top and bottom edges of the projections, as at 78 and 79. The top bevels 76 of the body are reverse to the top bevels 78 of the projections, and the bot-tom bevels 77 of the body are reverse to the bottom bevels 79 of the projections.

The operation of my machine is as follows: Suppose it be designed for use on a street-car to indicate the names of the cross-streets on the route, and such streets were numbered and ran from 1st to 28th street. In such case fifty-four indicating-plates would be provided, which would be arranged in the chambers 52, twenty-seven in each, as shown in the dia gram Fig. 12, beginning with 1st at the front of chamber 50 and running back to 27th at the rear, then down to chamber 52, and be. ginning at 28th in the rear and running forward to 2nd in the front. 1st and. 28th being the end numbers, it is unnecessary to duplicate them. The indicating-plates go around always in the direction of the arrow, the course being down passage 54, back through chamber 52, up passage 55, and forward through chamber 50. Thus it will be apparent that asa car is going out, thestreets indicated will be from 1st to 28th, and when returning, from 28th to 1st, by simply moving the indicatingplates around in the order of their arrangement. This movement is accomplished as follows: The cord 11 is pulled and draws the le- .ver 10 around, the spring-pawl 24 slipping over the rack 22. This turns the shaft 6, .which, by means of the bevel-gearing 7 8, turns the shaft 9, which, by means of the gear wheels 18 20 and pinions 17 19, turns the shafts 15 16, and they, by means of the lugs 64 69 and arms 66, oscillate the shafts 59 and 66. The pushers push the row of indicatingplates 51 in the chamber 50 forward the thick ness of one plate, and the pushers 65 push the row in chamber 52 back the same distance. This causes the plate 1st to pass over the edge of the chamber 50 into the passage 54, Fig. 13,

where its ends project into the path ofthe spring-hooks 35, which, being drawn down at that instantby the action of the pinions 40 on the racks of the slides 33, catch on the ends 75 of' the indicating-plate 51 and carry it down through the passage 54 onto the springs 71.

At the same instant the plate 28th is carried up by theslides 42 in the same mannerfrom the chamber 52 through the passage 55 to the chamber 50 at the rear of the machine. The pushers 65 70, after acting on the rows of plates, are retracted by the springs 62 68, so

as to be out of the way of the plates which are being transferred from one chamber to the other. The spring-holders 57, Fig. 11, project into the passage 54 and into the path of the plates 51; but when a plate descends its lower bevel, 77, workingagainst thebeveled ends of the holders 57 forces them back sufficiently to allow the. plate to pass. While the plate. is passing, the holders bear against it with a yielding but constant pressure, and hold. it with suflicient friction to keep it from falling and to require it tobe drawn down by the hooks 35, and thus prevent it descending more rapidly at one end than the other and becoming jammed in the machine. The long sides of the holders 57, being downward, prevent the plates from being carried upward on the return movement of the slides 33 by their friction against it. The springs 71 are placed so as to permit;

a limited movement of the plate below the floor if of the chamber 52, so that the plates 51 may certainly be carried past the spring-holders in boxed section 53. Then the pushers 65 push it back into the chamber 52 beforethe springs 71 react sufliciently to carry it above thecham her 52. The holders 58, having their long sides upward, support the plates 51 as they are carried up to the chamber 50, and prevent them from being carried down again by the retraction of the slides 42. They also hold the plates always in position to be engaged by the slides.

The beveled form of the spring-hooks 35 and 44 is for the following purpose:

Referring now to the hook's35, Fig. 10, the row of plates in the upper chamber, 50, when pushed forward by the pushers 70,-stand in the path of the ascending slides 33, the top bevels 36 of the spring-hooks encounter the lower. bevels 79 on the projections 75 on the ends of theplate. If the spring-hooks 35 were permitted to spring up, when they passthe. projections 75 of the plate they would cut and Wear each other to such an extent that the hooks would be unable to engage the plates, and so impair the proper operation of the machine. To obviate this danger I have provided the spring-pawls 39, Fig. 7, which project intothe grooves 32 in the path of the hooks 35 at a point which willcause the bev els 36 on the hooks to encounter the pawls and depress the hooks before they have passed the 'cdges of the projectionst75 of the plate. The

pawls 39 hold down the ends of the hooks until the latter pass clear beyond the upper edges of the projections 75 of the indicating-plate. Then the upward movement of the slides causes the pawl's to pass over the beveled ends of the caused to descend in the grooves 32, which movement causes the bevel 37, acting upon the beveled ends of the pawls 39, to force them back and permit the downward passage of the slides. As the slides descend,-the hooks 35 catch on the projections 75 on the ends of the indicating-plate, and carry the plate downward, as before described. The operation of the spring-hooks 44, Figs. 9 and 10, is precisely similar to that described with relation to the hooks 35, the only'difference being that the hooks 44 work from the bottom upward, While the hooks 35 work from the top downward.

As described, the indicator-case is fitted to receive only fiftyfour indicating plates. I construct it, however, for use with a greater or less number. 1n the present instance fiftyfour is the minimum number; but the case is capable of being adjusted to receive and operate a greater number in the following way: The boxed section is divided vertically into two parts, (see Figs. 10 and ll,) 80 81, which are connected by extension-slides 82 83, the slides 82 forming the floor of the ch'amber and the slides 83 the top of the chamber 52. The horizontal parts of the guides 56 are also formed of extension-slides 8485. The part 81. carrying the shaft 16 and its wheels 19 49 49, is fastened to a movable frame, composed of two upright pieces, 86, Fig. 8, next to the ends 4 and 5 of the case. The ends of the shaft 16 extend through the pieces 86, and are journaled in sliding boxes 87, placed in slots 89 in the end pieces 4 and 5. The frame 86 is secured by set-screws 90, extending through slots91, Fig. 2, at both ends of the machine,

when it has been adjusted to the proper'depth to contain the necessary number of indicatingplates. As the movement of the frame 86 will changethe position of theshaft 16and its pinion 19, it will disconnect the pinion l9from its driving gear-wheel 20. It is therefore necessary to adjust the latter correspondingly, and this is done by slackening the set-screw 92, Fig. 2, and moving the gear-wheel 20 along the shaft 9 to the required position and then tightening the set-screw. I have, however, made the adjustment of the wheel 20 automatic by extending a strap, 93, (see Fig. 2 and dotted line, left-hand, Fig. 8,) from the side of the frame 86 out to the back side of the hub of the wheel 20, as shown in Fig. 2. Then when the frame 86 is moved outward the'strap 93 moves the gear-wheel 20 along the shaft 9 and keeps it always in gear with the pinion 19, and when the frame 86 is moved inward the pinion 19, pressing against the gear-wheel 20, moves it along the shaft. The gear-wheel 20 is connected to the shaft by a feather, 94. When the frame 86 is moved inward or outward the extensionslides 82, 83, 84, and 85 open or close, and always preserve a smooth running or guiding surface for the indicating-plates to move over. On the shelf 25, at the rear end of the rack 22, is a single tooth, 95, Figs. 3 and 5, having an incline running reversely to the inclines of the ratchet 22. The purpose of this. tooth is to catch on the pawl 24, Fig. 5, and prevent the'operator from pulling the arm' 10 forward before it has had time to reach the end of the shelf and engage with the ratchet 22. The advantage of this arrangement will be apparent from the following explanation. 1f the operator pulls the cord before the arm 10 has reached the back end of the rack, no movement of the plates will be made in the machine,-for the reason that the transferring devices have not gone far enough to catch the ends of the indicating-plates, and consequently if the arm is pulled they will move without transferring the plates. If, however, the arm 10 is drawn forward just before it leaves the shelf 25, it may happen that on account of the wear of the plates or want of accuracy in fitting the machine one of the spring-hooks has reached a position in which to engage its end of the indicating-plate,while its companion hook has not. In such case the drawing of the cord would cause the indicating-plate to be moved at one end and not at the other. This movement would bring such indicating-plate into a diagonal position in the vertical passage, and would cause it to jam and prevent the further operation of the machine. I have therefore provided the single tooth 95 at the rear end of the shelf 25, so as to make it impossible for the arm 10 to be drawn forward just before it finishes its return-stroke. In this way I prevent the danger from this source. The shelf 25 is of such length that when the pawl 24 has passed over its rear end and the disk has been forced up so as to bring the pawl into gear with the ratchet 22 the hooks 35 and 44 have passed beyond the projections 75 on the indicating-plates, and are in position to engage therewith.

The pushers and are caused'to strike the plates 51 below their centers in order to avoid tipping them, and ,for the purpose of giving clearance to the pushers I have cut out' or recessed the plates at 96 97, Fig. 14', so as to permit the pushers to engage the preceding plate for a longer time before being retracted out of the path of the vertically-moving plate. The object of this'is to enable the preceding plate to get a better footing in the chamber before the pressure is taken away.

As the indicating-plates for some uses require to be made of considerable length, I propose to construct them, as shown in Fig. 14, with thick metallic end pieces, 98, and thin flexible center pieces, 99, preferably made of tin or sheet iron and properly attached to the end pieces. The pushers and spring-holders will becaused-to act against the surfacesof to transfer the indicating-plate from one hori- I the thick solid endpieces. These plates rest and slide ingthe chambers 50 and52 upon the solid end pieces. I also propose to counter sink that portion of the plate which contains the name, or, in casethe plate is made, as in Fig. 14, to set the thin center back from the front faces of thethick ends. The purpose of this is to prevent the rubbing off of the name as the plate passesaround in the case.
